I poked around a little more and found that the pin for the Z motor enable was set to "FORCE OFF" on STOP. I changed it to "No Change", and that seems to have solved the problem.

I have just completed my long-planned ballscrew installation on my Z axis, and in setting it up and testing it I did a lot more homing than usual.

The issue I have found is that if i either Ref All, or just Ref Z, the first time after starting Mach4, the homing routine works normally.

If i then hit Ref All again, X and Y (and A) will home normally, as they should, but Z does not move at all.

I can get it working again by jogging the Z axis first away from, and then into the limit switch(which usually does NOT cause the axis to stop or generate a reset while the system is having this problem).

If I then jog off of the Z++ switch, and press Ref All again, it will then home normally, first Z, and then X and Y.

Error message History shows, "!!!!!!!ESS: Homing Prep FAILED for Axis 2 - ESS Motor 2 - MOTOR NOT ENABLED!!!!!!
-----ESS: ERROR!  No ESS Motor being homed!!! Homing will probably not work..."

But the Z axis (Motor2) IS enabled, and will move with my MPG, Gcode commands via a program run or MDI, etc.

Similar results when I just Ref X axis.....

I have never noticed this behavior before, but I usually only home once a session, so it may have been there all along..

Any ideas?

I'm going to post to the Warp9 board as well...

System specs:

Mach4 in 4-axis Mill mode

ESS plugin V253

Windows 10 Pro Version 1809

I use combination limit/home switches. I have a switch at each extreme of travel for X and Y, and a single limit/home switch at Z++. A axis has no switches and is set to Home in Place.

"Home Order" has Z as "1", and X, Y and A as "2"My homing is set up with Z as priority

I just went through all the codes shown in my "Modals" line, and the following codes are there, but don't appear in the Mach4 Lathe reference:

G15, G49, G67, G69, G90

I'm not sure what you mean by that.

Thanks for this info.

So then, why does the status line in Mach4 Turn show G90?

When I try to execute a G91 from the MDI window, I get "Unknown G code used" error.

The Status line still shows the machine is in G90 mode.

and today, cutting more of the same part, the red axis centerline is not there at all!

I tried changing colors in the toolpath, to make the axis and the rapids look different.

Axis was already set to Yellow, but as you can see in the screen capture in the original message, it is displaying in Red. Changing axis color is config/mach/toolpath does nothing.

I am cutting a part that I have made a bunch of times with Mach3.

Using Mach4, the part cuts correctly, but the Toolpath Display in Mach4 doesn't look like what the tool is actually doing.

See the attached files for the toolpath display, and the actual profile of the turned part.

EDIT: Now that I posted the question, I see what is going on. I was viewing the bottom red line on the toolpath display as the part centerline; it is actually the top red line that is the centerline.

But, another question-I don't see how to make Mach4 "color in" the toolpath drawing as it does the motions, like Mach3 did. Is this feature there, and I just haven't found it?

yup, the forum auto-:corrected: the "eight, close parentheses"

My VFD is a Hopewind HV300.
